Problem : Unable to disable airplane mode. It says use hardware switch to turn off.

OS : Ubuntu 20.04.1 LTS

Laptop Model : HP 15 r074tu

Description : The lid sensor of of laptop is not working. In windows I use Fn + F12 key to toggle airplane mode and it works, but ubuntu I am not able to toggle, it boots up with airplane mode enabled by default. Is it possible that it is happening because of lid is not working. I have seen threads mentioning people having problem of airplane mode where lid operation set to suspend.

What I have tried :

The mentioned solution worked: Edit your kernel boot parameter with: sudo nano /etc/default/grub

Look for the line with GRUB_CMDLINE_LINUX_DEFAULT="quite splash acpi=off" <--parameters may defer based on your system - -> Within the " " (quotes), replace acpi=off or any other acpi parameters with acpi_osi=!.

e.g.: GRUB_CMDLINE_LINUX_DEFAULT="quite splash acpi_osi=!"

Press Ctrl+O to Save and Confirm Change Press Ctrl+X to return to terminal

Update grub with : sudo update-grub

Reboot your machine
